I've downloaded the latest demo build of x64 Edition, as I'm thinking about switching over to x64 from 32 bit XP, but it's nice to be able to "try before you buy", and it also means I can try the 64 bit versions of HL2, UT and Far Cry.

I'm assuming most 32 bit stuff will work with a bit of fiddling, but is it worth going with x64 or should I stick to "Regular XP"

I've got no driver issues as 64 bit ones are available which is a relief
